Daesh (ISIS) is not Hamas or PIJ. I mentioned nothing of them, you're putting words in my mouth. They could not be further from each other, and it is incorrect to equate them.
It's wrong to say that no one cares. Many, many Muslims have spoken out, and there are many humanitarian efforts being run.
The fact of the matter is that the middle east is still in the shadow of colonialism post WWI. Every time there is an effort to unite, there is immediate intervention by the west, in order to preserve their interests. We saw what happened in Egypt for example when Mursi was elected. It is in the vested interest of the west for conflict to continue in the ME. joe biden is on record for saying that if there was no israel, they would have to create one.
